Hi All,
I want to do a curve fitting for an LED I-V characteristics based on an LED model:
I - (V - I*Rs)/Rp = Is* (exp(q*(V-I*Rs)/(n*k*T))-1)
I have a series of corresponding V and I values:
V = [2.65462
2.80218
2.88911
2.94203
2.97592
3.00377
3.02513
3.04314
3.06204
3.08061
3.09944
]
and
I = [0.001
0.005
0.01
0.015
0.02
0.025
0.03
0.035
0.04
0.045
0.05
]
Assume T is known, say, T=350
I need to get the values of Rs, Rp, Is and n. I am a beginer of Matlab. Please do me a favor to show me how. Thank you so much.
